Web application security in a crossing boundaries grid system
Serena Pastore · 2007
The grid problem is how to enable coordinated resources sharing and problem solving in dynamic, multi-institutional cross organizations called Virtual Organizations (VOs) that collect a large number of nodes grouped into grid sites. An overlay of policies governs access within a collaboration that is granted to users by a VO and by a site to VOs, nodes and users through site admission-control policies. Most resources consist of web applications and web services shared by a site that is part of a VO. The paper proposes an analysis of web application security by referring to XML-based applications accessed through a grid system. The different organizational domains involved transfer security from grid-wide to the VO level, and from the site and machine to the application level in order to allow local control to be retained.
